I might get “cancelled” for this, but hear me out:
If you remove your account bad actors won’t be able to identify you unless they put in the effort. Reddit staff will revert popular comments and posts to the way they were before the Blackout. Mass-scrambling your posts and comments with a “f*ck Spez”, followed by a long chain of "A"s or whatever, annoys people who are just trying to find an answer to something on Reddit, and it doesn’t help anybody except the user’s feelings.
The preservation of information comes above some moral feeling.
Your opinion?
I want someone to add a markoff chain generator to a plugin like “So long reddit thanks for all the fish” so that I can properly trash my 225k comments in a way that will break AI crawlers & search engines.
